i'm thinking there is no crank number on an electric as there is no loss in direct drive... so it is producing 428 HP???

A dyno does not measure HP at the crank. What you see displayed is wheel horse power. "Your results may vary" as they say, due to different types of dynos, weather conditions, battery pack temp and condition etc.

Is it safe to say that that's comparable to a 500hp ICE, assuming 85% wheel/crank efficiency for a typical ICE?

but it could be compensating for things that don't apply to the tesla so the number may be skewed. wish they put little more info in the video!

If its on a dyno, it's RWH.

@eddiemoy: Exactly. Dynos usually include a number of corrections that may or may not apply to a BEV such as ambient temperature. Still a great number, though.
